I re-posted the 'evidence' as a separate thread because it seemed like some of the people who looked at the earlier one were stopping when it looked like there was no 'proof.' and I also had no indication or reason to believe that there was anything being looked at or done, to fix it.

I had a similar type of "it works fine for me"/"I can't duplicate that problem" exchanges with Khaled almost 6 years ago, when 5.61 was having some problems with the tooltips causing system freezes/crashes. I was right then too, although it took a while before anyone else - including Khaled - believed it.

I didn't give up then, and I'm not giving up now. Although it seems possible that the problem won't actually get fixed until one of the developers stumbles across the relevant area of code by accident. It doesn't seem like many people actually use the Buffer-->Save As... function (as opposed to continuous logging, for example), or if they do, they haven't noticed the problem yet.
